Detailed Explanation of Key Techniques for Protected Cultivation of Wax Apple
Wax apple has been a relatively popular fruit in recent years, and there are now many cultivation models for wax apple, among which protected cultivation is quite common. Protected cultivation of wax apple facilitates the daily management of wax apple growing and helps improve the yield and fruit quality of wax apple. So how should we go about growing wax apple? Below, the editor brings you the key points of protected cultivation of wax apple. Let's take a look!
1. Selection of Wax Apple Seedlings
In protected cultivation, because the height of the greenhouse is limited, the selection of wax apple seedlings is very important. When choosing wax apple seedlings, we should choose air-layered seedlings or grafted seedlings. This type of seedling has relatively less vigorous growth. Even when it reaches the production period, the tree will not grow too tall, making it more suitable for management in a greenhouse environment. Therefore, it is not advisable to choose seedling trees, as seedling trees not only have a longer production period, which affects costs and benefits, but also have a relatively tall tree form, requiring more investment in the greenhouse.
2. Environmental Regulation
During the cultivation of wax apple, temperature is very important. During the day, the greenhouse temperature should be controlled at around 28 degrees, and at night the temperature should be appropriately lowered by about 8 degrees. In winter, the minimum temperature inside the greenhouse should not be lower than 10 degrees, to avoid frost damage to wax apple. When the temperature is too low, heating should be carried out in time to protect against cold, and when the temperature is too high, ventilation should be carried out in time to cool down. Then the humidity inside the greenhouse should be well controlled, maintained at around 70%-75%, to prevent excessively low air humidity from reducing the number of flowers and fruits of wax apple. Finally, the carbon dioxide concentration inside the greenhouse is also quite important; if the concentration is too low, it will affect photosynthesis in wax apple. Therefore, attention should be paid to supplementing carbon dioxide inside the greenhouse.
3. Water Management
The root distribution of wax apple is not very deep, and it likes to grow in a moist environment, with relatively poor drought resistance. Therefore, during the growth period of wax apple, attention should be paid to frequent watering to maintain the soil moisture content and meet the water needs of wax apple. However, attention should also be paid to the amount of watering to avoid water accumulation, which affects root respiration and reduces fruit quality. At the same time, intertillage and soil loosening should also be done well to improve soil permeability and promote root growth. During the fruit ripening period, the amount of watering should be well controlled, and the soil only needs to be slightly moist.
4. Scientific Fertilization
Wax apple grows relatively fast, and its annual growth amount is also relatively large. Therefore, its demand for fertilizer is also relatively high, so in addition to applying sufficient base fertilizer each time, we must also do a good job of topdressing. Organic and inorganic fertilizers should be applied in combination, with soil fertilization and foliar fertilization cooperating with each other, and attention should be paid to supplementing trace elements and high-quality organic fertilizer. However, attention should be paid to the content of harmful gases such as ammonia inside the greenhouse, to prevent excessive content from affecting the growth of wax apple. It is also necessary to ensure that farmyard manure is fully decomposed, and to control the amount of fertilizer applied, to avoid excessive fertilization causing fertilizer damage to the crop.
